how to return an object from a key

December 6, 2021

I am trying to return an object based on a key, I managed to do that with the method below but still, I am wondering how to return the key and value 250: [176916, 176922, 176939], instead of the value only [176916, 176922, 176939]

const myObj = {
  250: [176916, 176922, 176939],
  325: [244050],
  400: [177100],
  500: [166743],
  700: [387789],
};

let arrAcceptedValues = [];
let notArrAcceptedValues = [];
const acceptedValues = ["250", "400"];

Object.keys(myObj).forEach((key) => {
  acceptedValues.includes(key)
    ? arrAcceptedValues.push(...myObj[key])
    : notArrAcceptedValues.push(...myObj[key]);
});

console.log({ arrAcceptedValues, notArrAcceptedValues });

//arrAcceptedValues result: [{250: [176916, 176922, 176939]}, {400: [177100]}]

>Solution :

Maybe this helps:

const myObj = {
  250: [176916, 176922, 176939],
  325: [244050],
  400: [177100],
  500: [166743],
  700: [387789],
};

let arrAcceptedValues = [];
let notArrAcceptedValues = [];
const acceptedValues = ["250", "400"];
Object.entries(myObj).forEach(([key,value]) =>{
    acceptedValues.includes(key)
    ? arrAcceptedValues.push({[key]: value})
    : notArrAcceptedValues.push({[key]: value});
});

console.log({arrAcceptedValues , notArrAcceptedValues })
